Here is the discussion of a few years ago of of the creation of world's first amateur FAMARS images and here is the complete set of the 158 images taken by Phoenix.

Dr. Dan Richman discovered extraterrestrial fat cell remains in meteorite Murchison as shown in Fig. 8 at

http://astrobiology.jhu.edu/wp-content/uploads/2011/02/2011-2-2-prebioticlipidsintro1.pdf

All fat cells (adipocytes) are filled nearly completely with lipids (fat globules, also called lipid droplets) as shown in this TEM:

Lipid droplets differ from red blood cells in that lipid droplets can have different sizes in an animal while red blood cells have same size in an animal.

News from the Atacama desert: [link]

The above report somehow reminded me of this discovery in turkey:

Both reminded me of Mawrth Vallis, Mars Smile

I saw the article about David Martines discovery. Did you notice how quickly it was disputed by "Experts" After seeing the article I decided to 'NOT' let it die. I'm an author and I wrote 31 Ocean-The NASA Files. It is a fiction novel that takes off about his discovery. I write on Amazon and Barnes http://www.amazon.com/-/e/B0043TC2O6. I reduced the electronic download price to 99 cents so people would read it. Take a look at it and let me know what you think. Pass it on...Sincerely KJ Nivin

Nice catch MPJ.

In the video it says craters are the best place to look, Eberswalde with an old river delta could link with these finds. The polygons and those white islands have been seen from orbit and by the MER's.

Does MSL have the right equipment to identify a microbe? I am not sure it has.

KJ Nivin we all smell the rat when it comes to any such suggestions of life elsewhere being shot down with vigour. Too much religion in this world not enough science.

Kevin, how I understood is that MSL can detect life-related chemistry and its products but and this is a huge disadvantage, cant distinguish wether it is related to current life or past life if it detects something.

regarding those fluffy bacterial created(grown) white rocks in the video in re250: albeit its stated in the clip this might have happened in martian craters I would look especially in ancient terrain not necessarily in craters with a sure watery past for such those Mawrth Vallis just remember this close-up somewhere in the MSL landing elipse 2:

see the white fluffy stuff between the dunes?

not to forget all the other peculiar things like this:

They really should send MSL to Mawrth if they want some extraordinary discoveries outside the box AND inside the box (mission goals) so to say Smile

Hi MPJ, I know you are a big fan of Mawrth and it is truly an interesting area, why they are not going there is anyones guess. Perhaps when the landing site has finally been chosed they will explain.

Rover scientists train their eyes for fossils in preparation for the MSL mission - way to go Smile

Kevin, I only hope that scraping Mawrth will be worth it. If not I hope there will be another mission to Mawrth during my lifetime Confused

Well at last they are going to actually try and find a fossil rather than skirting around the issue. Pilbara is an interesting area when viewed on Google Earth, plenty of geological layers.

Nice catch anyman! Interesting the Dawn probe went into orbit around Vesta yesterday, I wonder what it might tell us over the next 12 months. Also a lot of meteorites found on Earth come from Vesta.

It also reminds me of this:

#174 It will be interesting to see how the private sector performs, big bold claims are going to be made. It is similar to private aircraft makers pitching for the next generation of fighter jet. In that scenario the one that loses the contract has to hand over a certain amount of its technology to the winner because it was part government funded. I wonder if the same applies to NASA part funded projects.

#175 True.

An ESA lesson of extant life on Mars from the viewpoint of the (possibly) upcoming ExoMars mission to Mars with notation by me in brackets:

[link]

"In 1976, the twin Viking landers conducted the first (and still ONLY) in-situ measurements focusing on the detection of organic compounds and life on Mars. The Viking biology package contained three experiments, all looking for signs of metabolism in soil samples. One of them, the Labelled-Release Experiment produced very provocative results (aka positive results - including the thermal control runs which should have eliminated only biologic not putative chemical responses). If other information had not been also available (which are now generally believed to have been flawed like the GCSM due to heat induced decomposition of organic compounds and the general lack of sensibility which on Earth also yielded false negatives in tests), these data could have been interpreted as proof of biological activity (and should now be reassessed!) . However, theoretical modelling of the Martian atmosphere and regolith chemistry hinted at the existence of powerful oxidants, which could more-or-less account for the results of the three biology package experiments (but not the nil responses of the LR thermal control runs). With few exceptions (guess who Smile ), the majority of the scientific community (aka NASA employed scientists) has concluded that the Viking results do not demonstrate the presence of life.

Numerous attempts have been made in the laboratory to simulate the reactions observed by the Viking biological package. While some have reproduced certain aspects of the data, none has succeeded entirely. Incredibly, almost 30 years after Viking, the crucial chemical oxidant hypothesis remains still untested (this is exactly the point Levin is always grumbling about - nothing more nothing less!). ExoMars will therefore include a powerful instrument to study oxidants and their relation to organics distribution on Mars (Levin will be happy I guess if he dont pass away before)."

Lets hope the ExoMars Rover will make it to Mars to give us a real clue about life on Mars at last which NASA failed to establish in the last 40+ years.

We have wasted so much time it should no longer be enough simply to seek to confirm life on Mars: we need to start studying it. IMO the best way to proceed is to send an experiment that can not just detect DNA, but can sequence it. If we could completely sequence a Martian genome, we could learn a lot about its relationship to Earth life. In principle we might ultimately even be able ultimately to replicate the organism. I wouldn't recommend doing this on Earth though, having seen too many SF shows in my youth!
